IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 29,858, dated September4, 1860.

- To all whom it may concern.-

Be it known that I, T. E. O. BRINLY, of

Louisville, in the county ofJetferson and State Kentucky,have invented anew and useful Improvement in Flows; and I do hereby declare that thefollowing is a full, clear, and exact description of the same,referencebeing had to the annexed drawings, making a part of this specification,in which Figure 1 is a side view of my invention; Fig. 2, a transversevertical section of same, taken on line .r 00, Fig. 1; Fig. 3, ahorizontal section of same, taken in the line 3 y, Fig. 2; Fig. 4, adetached inner-side view of the standard.

Similar letters of reference indicate corre sponding parts in theseveral figures.

This invention consists in a novel and improved way of attaching thestandard of the plow to the mold-board and landside, as hereinat'terfully shown and described, whereby a very firm and durable attachment isobtained,

, and one that .will admitof the standard being readily detached, itbroken, and a new one adjusted in its place;

To enable those skilled in the art to fully understand and construct myinvention, 1 will proceed to describe it.

A represents the beam of the plow, and B B the handles.

0 is the mold-board, and D the landside, a handle, B, being attached toeach, as usual.

D is the standard, which may be of the usual form or shape, but having.at its inner side a ledge or projection, to, which forms arest orhearing for the beam A, as shown in Figs. 1 and 2. At theinner side ofits standard there is also a lip or projection, b, which has a curved orcone-ave front surface corresponding to the curvature of the back sideof. the mold-board O. This curvature of the projection bis shown clearlyin Fig. 4, and the projection is secured to the mold-board by aserewbolhc. The outer side of the standard has a shoulder, d, which isformed by a recess at its lower part, as shown clearly in Fig. 2. Thisshoulder rests on the upper edge of the landside. D, and a bolt, 6,passes through the lower part of the standard and landside. The upperend of the standard passes through the beam, and a key, f, passesthrough the standard above the beam. The upper end of the lip orprojection 12 projects over backward in curved form, as shown at g, andthe lower end of a rod, E, catches over it, the upper end of said rodpassing through the beam A and a metal head, It, thereon, and has a nut,i, on it. The rod E serves as a brace for the standard, the rod beingstrained perfectly taut by screwing up the nut 0). By having the lowerend of the rod E hooked over the lip or projection b it will be seenthat the standard is not weakened, as has hitherto been the case byholes formed in it to receive the brace, and by having the standardprovided with the ledge or projection to and shoulder h, and theprojection 72 secured to the mold-board, as described, a very firm andsubstantial plow is ob tained.

F is the cutter, which projects up in front of the landside D. Thiscutter is attached to or formed on a plate, j, which is of the same formas the landside, and is fitted snugly to it and secured thereto by bolts6 70 l, the former of which, 0, secures the lower end of the standard tothe landside, and the bolt 70 secures one of the handles to thelandside. The front end of the platej is fitted to thelandside by adovetail joint, m, as shown clearly in Fig. 3. This dovetailjoint firmlysecures the front end of plate j to the landside. I

The cutter andplatej may be made of steel, and by being thus arrangedand secured to the landsideadd greatly to the durability of the plow.

- The mold-board may be of steel; but the standardD,in consequenceofbeing constructed and arranged as shown, may be of cast-iron.

Having thus described my invention, whatl claim as-new, and desire tosecure by Letters Patent, is

The arrangement on the standard D and beam A of the ledges a b andshoulder h, to admit of the attaching of the standard to the landside,mold-board, and beam, as shown, in connection with the brace or rod E,applied substantially as and for the purpose set forth.
